You can see the ledge with the items in the screenshot above. The crevice on the left is how to get there. It doesn't look like a crack you can grab, but if you look farther to the right, you can see where it widens.
Turn left, so the lava pool is on Lara's right and walk forward until Lara touches the wall. Take one hop back, then sidestep as far as possible to the right so Lara's right foot is at the edge of the pit. Now turn about 10 degrees to the right so Lara is facing the wall just above and to the right of the edge, as shown in the screenshot above. Take a standing jump to grab the horizontal seam in the wall.
Traverse to the right all the way over the lava pit and drop down into secret #2.
